An aerobatic aircraft is limited to \( +6 \) g. If it stalls at \( 40 \) m/s level, its corner speed is nearest to

  • A.80 m/s
  • B.60 m/s
  • C.98 m/s
  • D.240 m/s

Answer: C

Multiplying by the square root of the limit factor, \( 40 \times \sqrt{6} = 40 \times 2.449 = 98 \) m/s. The higher structural limit pushes the corner speed much further out than a transport's, which is exactly what makes tight aerobatic manoeuvres possible.
